JimW, HugoP,

With the recent blend design activities, a lot of filter files (.mat) were created, some were duplicated multiple times in the folder tree, while only a few were actually used. Some filters were also installed in the wrong slot, with the wrong name. For example: Start filters were installed in ITMX's TCrappy, TBetter was installed in ETMX's TCrappy. This can be quite mis-leading for the commissioners and we should avoid it.

We figured out which filter files should be used. We took those and gave them clear names in the common BSC part of the seismice SVN as follow, and removed every duplicate we found in the folder tree:

/ligo/svncommon/SeiSVN/seimic/BSC-ISI/Common/Complementary_Filters_BSC_ISI/aLIGO/

• Start:
  Start_Filters_BSC_ISI_2014_02_25.mat  ->  Start_Blend.mat
• T750mHz:
  uses Start_Blend.mat, generic routine automatically adds the trillium to the blend.
• TCrappy:
  some_blend_crappy_fitlers.mat   ->  TCrappy.mat
• TBetter:
  some_modified_blend_crappy_fitlers_040914.mat  ->  TBetter.mat

The Step_6 unit-specific scripts were modified for each BSC-ISI chamber to prevent accidentaly loading the wrong filter into the wrong slot again.

Every BSC-ISI blend filter was reloaded this morning at 9:35AM, from the agreed generic blends mentioned above.

Work will be commited to this SVN today, to facilitate next week's commissioner hand-off.
